Hi,
While running kselftest on vanilla torvalds tree kernel commit v6.8-11167-g4438a810f396, the test suite reported a number of errors.
I was using the latest iproute2-next suite on an Ubuntu 22.04 LTS box.

The problem is present at least since 6.8-rc7.
Please find attached the config and the full output of test_vxlan_mdb.sh.
Hope this helps.

Hi, Hangbin,
I am running an Ubuntu 22.04 LTS configuration.
I tried it again with 6.8.0-net-next-05204-g237bb5f7f7f5 and iproute2-next from this repo: https://git.kernel.org/pub/scm/network/iproute2/iproute2-next.git

Hi, Hangbin,
I am running an Ubuntu 22.04 LTS configuration.
Didn't get your first mail for some reason. Anyway, it might be related to the fact that Ubuntu is using an old version of libnet:
https://launchpad.net/ubuntu/+source/libnet
I remember fixing similar issues in the past:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
Will look into it today or later this week.

Your organisation's Office 365 is configured against compressed attachments:
Diagnostic-Code: smtp;550 5.0.350 One or more of the attachments in your email is of a file type that is NOT allowed by the recipient's organization.
I will try to remember this.
Anyway, it might be related to the fact that Ubuntu is using an old version of libnet:
https://launchpad.net/ubuntu/+source/libnet
I remember fixing similar issues in the past:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
I recall that last August.
Will look into it today or later this week.
Thank you for considering this.
